Original Io. 1,551,184, dated August 25, 1925, Serial No. 674,638, filed November 14, 1923. Application for reissue filed April 21, 1927. Serial No. 185,605.

This invention relates to improvements in railway crossing structures, and is a modification of the structure originally shown and claimed in my prior Patent 1,154,534, patented September 21, 1915.

In the present form I have provided approach plates coactable with the outside of the rails of a track and an intermediate plate constructed to bridge the space between the rails, these elements being varied in form and arrangement to accommodate various track layouts. In the present embodiment,

I have constructed my plates to permit securing of the intermediate plate in position between the rails without spikes or other through fastening means, permitting disposition of the plate without regard to the location of the cross-ties, which is necessary where through spikes or the like are used.

Another object of my invention is to provide a structure-of this character which may be positioned without interference from the rail joints or tie-plates, this being accomplished by the provision of integral lugs which may be knocked or chipped of! from the supporting flanges.

, Another ob ect consists in the provision of an approach plate which will interlock with or engage a track rail so that with the assistance of ordina spikes driven in the ties at the side of the plate opposite to the rail the approach plate may be held securely in osition.

he purpose of these plates is to carry a roadway or other crossing over a track in such wise that access to the track or roadbed may be readily had in order to permit the crossing of the track to be laid with a minimum of expense and labor, eliminating the 40 use of planks, concrete or the like, now in general use.

These and other objects will be more fully set forth and described in the following specification and shown in the accompany ing; drawing, in which igure 1 1s a plan view showing my railwaly crossing as applied toa single track.

igure 2 is a vertical section along line 2-2 of Figure 1.

In the drawin s, 10 designates, generally, the ordinary Ts aped rails having the head portions 10" and the base flanges 10" and 10 extending to outside of the central web 10.

' These rails 10 are carried on the usual transverse sleepers or ties 12. In the form shown,

construction, and including a chair or tie the track is secured to ties 12 by tieplates 13 of conventional construction, and I have illustrated such a rail joint, generally indicated by numeral 14, also of conventional plate member.

Extending between-the rails 10 is the intermediate plate member, generally indicated by numeral 15, and comprising a bod or supporting portion 15 provided wit cross ribs or corrugations 15 to eliminate danger of slipping. Extending downwardly and outwardly from the upper supporting portions 15 are the side flanges 15. Between the slde flanges and formed integral therewith and with the upper'portion 15 are the strengthening ribs 15 serving to strengthen and re-inforce the structure. At their supporting edges the flanges 15 are provided with lugs 15 (see Figure 1) which may be broken or chipped off, as desired, thus permitting the flanges to rest upon the base pt the rails without interference from ra l oints or'tie plate members, the la s being broken away to accommodate suc members, as shown, for example, in Figure 2.

To secure the intermediate late 15 between the rails, I provide we ges or filler blocks 17 of Wood, or the like, which may he slid longitudinally of the rail into position beneath the head of the rail, these members 17 coacting with the rail heads and the flan cs 15 to prevent vertical displacement of t e supporting plate 15, the lugs 15' preventing movement longitudinally of the track.

In use with a single track; as shown in the drawing, I provide an approach plate 20 at the outer side of each rail, these approach plates being provided with the upper corrugated supporting surfaces 20' and the vertical depending flanges 20 and 20, the former having an angularly directed base plate 20, Intermediate the ends of the approach plate 20 the flange 20 is inset to provide a recess 20 for the accommodation of the rail joint or similar member. At the sides of the recess 20 the flanges 20 is projected outwardly of the plate 20 to fit beneath and engage the rail head 10 as indicated at 20. The portions 2O of flange 20 are continued downwardly to rest upon the base plate of a rail and are maintained in position by spikes 25 or the like engaging the portions 20 of flanges 20 to preno vent outward displacement should the roadway fail to prevent such displacement.

It will be obvious by the structure above described that I am enabled to provide a strong crossing between and at the sides of a track which may be economically constructed of cast iron and which is capable of being quickly removed for replacement or access to the roadbed in contra-distinction to planks; concrete, or the like now generally used. It will also be apparent that these plate members may be laid without interference from the rail joint, tie-plates, or the like, thus permitting ready application to existing trackways.

I do not wish to be restricted to the form shown and described, except as defined in the appended claims.

What I claim is:-

1. In combination with a pair of rails, a plate member extending therebetween, said plate having depending supporting flanges,

and wedge members inserted between eadh rail and the adjacent flange.

2. In combination with a pair of rails, a

v plate member extending therebetween, said plate having depending outwardly inclined supporting flanges, and wedge members inserted between each of said rails and the adjacent flange.

3. An article of manufacture comprising a railway crossing plate having an upper supporting portion, and depending supporting flanges, said flanges being provided with removable lugs at their supporting edges.

4. In combination with a pair ofrails havin base flanges, and a plate member exten ing between said rails, said plate member having depending supporting flanges resting upon said rail flanges, and members coacting with said rails and said plate members to prevent vertical displacement of said plate members.

5. In combination with a pair of rails having base flanges, and a plate member extending between said rails, said plate member having depending supporting flanges resting upon said rail flanges, and means coacting with said rails and said plate members to prevent vertical displacement of said plate members, said last named means com prising wedges located beneath the heads of said rails.

6. In combination with a track rail, a crossing plate arranged to have its upper surface substantially at the same level with the rail head, said plate being formed to engage the rail against vertical and lateral displacement, including a downwardlydisposed supporting flange formed with arecessed portion to fit beneath the head of said rail and braced at one edge thereof.

7. In combination with a track rail, 8.

crossing plate arranged to have its upper surface substantially at the same level with the rail head, said plate being formed with a portion to engage the rail against vertical and lateral displacement, including adownwardly disposed supporting flange wedged between the rail head and the base flange thereof.

In combination with a track rail, a crossing plate arranged to have its upper surface substantially at the same level with the rail head, said plate being formed to engage the rail against verticaland lateral displacement comprising a downwardly disposed flange including a rail head engaging portion and a base flange engaging portion adapted to ride upon the inclined face of said rail base flange to brace the plate flange between said rail head and base flange and forming the sole support at one side of said plate, and means for anchoring the opposite end of said plate.

9. In combination with a track rail, a crossing plate arranged to have its upper surface substantially at the same level with the rail head, means for engaging the rail to hold one end of said plate against vertical and lateral displacement comprising a downwardly disposed flange including a rail head engaging portion and a base flange to hold one end of said plate against vertical and lateral displacement comprising a flange including a rail head engaging portion and a base flange engaging portion adapted to be positioned b pivotally moving the same upon the inclined face of said rail base flange to brace the flange between said rail head and base flange, and means for anchoring the opposite end of said plate said base flange engaging portion and end fclirmin'g the sole supporting means for said p ate.

11. In combination with a pair of rails, a
